I would want another bat. They can't go into next season w/o addressing either black hole in the lineup. Calhoun is an adequate stopgap if they address DH IMO.
Give me JDM or Grandal to DH, Calhoun or similar quality stopgap for RF, one starter a tier below Cole/Strasburg, and one backend innings eating starter to go with a few pen arms and I'll be happy. Anything less will be a disappointment IMO
